ECS performent collision
I am looking into making a demo project using ECS, consisting of a whole bunch (couple hundred at least, hopefully a couple thousand) ships in space, shooting at eachother, with varying sizes of ships and bullets.
I looked at the Unity ECS Physics project on Github, and while looking at the CollisionUT project, bumped up the number of dynamic cubes to about 400. While I am impressed they have collision for ESC at all, I was disappointed to see my frame rate drop to 7 when the cubes hit the floor.
So, clearly that demo does not support mass scaling. But how would I get performent collision detection using ECS?
PS: we need an ECS / Entity Component System tag for topics
I just reviewed the Unity at GDC $$anonymous$$eynote 2019, and at 1:33:36 into the video they start talking about the physics, and show off the Unity/ Havok physics. so... I'll be looking into that project for inspiration. I would still like to know if anyone has any ideas about how to use the physics components, in lieu of comprehensive API and recent (summer 2019) ECS Physics tutorials.
